+1 I wasn't aware that this module is obsolete and was trying to start it a few weeks ago. We develop a home-made solution some time ago to monitor smart data from both HDD (uncorrected errors, grown defect list) and SSD (WLC/TBW). But keeping it up to date with non-unified disk models is a nightmare. Alert : "OSD.12 is going to fail. Replace it soon" before seeing SLOW_OPS would be a game changer! Thanks!

Hi.
From our point of view, it's important to keep disk failure prediction tool as part of Ceph, ideally as an MGR module. In environments with hundreds or thousands of disks, it's crucial to know whether, for example, a significant number of them are likely to fail within a month - which, in the best-case scenario, would mean performance degradation, and in the worst-case, data loss.
Some have already responded to the deprecation of diskprediction by starting to develop their own solutions. For instance, just yesterday, Daniel Persson published a solution [1] on his website that addresses the same problem.
Would it be possible to join forces and try to revive that module?

Hi everyone,
On today's Ceph Steering Committee call we discussed the idea of removing the diskprediction_local mgr module, as the current prediction model is obsolete and not maintained.
We would like to gather feedback from the community about the usage of
